Thunderstorm Wind in Uintah County, Utah

With just enough moisture to work with, showers and thunderstorms began to form on the higher terrain around the Uinta Basin early in the afternoon of August 7. These storms received some upper level support in the form of a passing shortwave and a modest upper level jet, which allowed them to become strong to severe. In addition, dry surface levels acted to boost already strong to severe winds. Winds recorded during this event ranged from 45 mph to the peak of 64 mph, which was recorded at a Utah State Climate Mesonet Site 9.1 miles east of Randlett. No reports of damage or injuries were received.

Just enough moisture and instability lingered across the higher terrain of eastern Utah and western Colorado to form showers and thunderstorms. The most intense convection was observed across northeast Utah and northwest Colorado, where a passing weak shortwave and a modest upper level jet provided additional lift and instability. The probability of strong winds was also enhanced by dry surface levels.
